Description
Technical field
The present invention relates to a kind of recovery method and system, more particularly, relate to a kind of recovery method and system of chemical recovery hydrocarbon resistates, heavy oil, various waste or organic substance that this resistates is for example discharged in oil refining process or the petrochemical process.
Background technology
The oil refining process General Definition becomes a kind of slowly the extraction than light composition from crude oil will have the process of the heavy oil of high C/H ratio as resistates as product.In other words, oil refining process can be defined as removing the process as the unwanted carbon component of heavy oil from crude oil.Therefore, the remaining heavy oil of from oil refining process, discharging for recovery and reuse are this, it is just especially important to handle these unnecessary carbon components effectively.
The easiest a kind of method of handling these surplus carbon compositions these carbon components that burn exactly.Pyrolysis and/or gasification also are feasible for effectively utilizing heavy oil.When heavy oil is overheated to carry out pyrolysis and/or when gasification, can further remove lighter composition by gasification.Final remaining carbon component is exactly fixed carbon (coal smoke and a coke).Therefore, in order to make heavy oil gasification, must adopt a kind of gasification process that can handle fixed carbon.
The speed of response of gasification is lower than burning.Especially, fixed carbon can gasify with very low speed of response.Therefore, in order to strengthen the speed of response of gasification, the gasification of heavy oil is carried out under High Temperature High Pressure usually.Particularly, the gasification of heavy oil is 1000 ℃ to 1500 ℃ temperature and carries out under the 1MPa pressure at least.Usually, come elevated temperature by the direct heating that utilizes partial oxidation, wherein a part of heavy oil and oxygen react.Can not adopt the method for indirect heating, carry out the heat exchange of high-temperature scope with heat exchanger because be difficult to.
This gas that gasification process produced with partial oxidation is mainly by H
2, CO, CO
2And H
2O forms.For these gases that produced of chemical recovery, then will be with H
2Separate with CO and utilize again as required.Perhaps, can be with the gas that produced as the combustion gas of gas turbine etc. and do not need to separate H
2And CO.Because the gas that produced is as indicated above to have higher pressure usually, it can directly be introduced in the gas turbine and not need further to compress, and will carry out gas-purification process or combustion gas refining process before being introduced in gas turbine.
For the gasification process of this use partial oxidation, vapourizing furnace at high temperature moves.Therefore, the heat-resistant components for example wearing quality of burner and refractory materials has descended, thereby has increased the cost of equipment and maintenance.Moreover, owing to use the gasification of partial oxidation under High Temperature High Pressure, to carry out, therefore need very high operation skill.Thereby running cost has also increased.Therefore, under many circumstances, make the size of the used gasification system of the high-temperature gasification process of partial oxidation be made very big, to obtain the advantage of scale and to reduce the initial cost burden.Usually, the initial stage drops into needs hundred million yen of hundreds ofs.
